Application March 30,

3 Claims.

, This invention relates to means for supplying air to the scalp of aperson having her hair yvaved, the general object of the invention beingto provide means for preventing burns to the scalp 5 while the hair isbeing treated for permanent waves.

This invention also consists in certain other features of constructionand in the combination and arrangement of several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several parts, and in which:-

Figure 1 is an elevation of the complete device.

Figure 2 is a sectional view through the 'casing for surrounding the fanand showing one of th air delivery members in elevation. I Figure 3 is abottom plan view of one of the members.

Figure 4 is a longitudinal sectional view through said member. I

Figure 5 is a side view of the lower part of the member.

Figure 6 is a view showing a modified form of screen of the fan casing.

Figure 7 is a detail sectional view showing how the screen is held tothe casing.

Figure 8 is a fragmentary sectionalview showing how the two sections ofthe screen shown in Figure 6 are detachably connected together.

In these drawings the numeral i indicates an upright stand having theyoke 2 at its upper end which is formed. with the inwardly extendingbearing parts 3 at its extremities for receiving the trunnions 4 of theblower shown generally at A. This blower includes the casing 5preferably of the shape shown in Figure 2 with its large rear end havinga screen 6 therein which is formed with an opening for surrounding themotor M of the fan F which is located in the casing. The small end ofthe casing is closed by a plate 1 which is provided with a plurality ofnipples 8 each of which is adapted to receive an end of a hose 9, theother end of which fits over a nipple ID on a casing or cap II, whichform part of the air delivery member. This cap or casing has a dischargeor outlet end of elongated form and relatively narrow with the end partsof the casing or cap converging to the nipple and the side partssubstantially flat. Thus the discharge or outlet end of 1935, Serial No.13,9 2?

the casing is of considerable length and narrow and said discharge oroutlet end of the casing is shown at I2 in Figure 4. A member 14 formedof rubber or composition of rubber has its upper end of substantiallythe same shape as the outlet end I2 of the casing I l and said end ofthe rubber member fits in a channel member l3 which in turn fits in thedischarge end I! of the casing. The member 14 flares outwardly, asshown, and terminates in a substantially straight or flat. part 10 I4 towhich ribs I5 are connected, these ribsbeing arranged as shown inFigures 3 and 4 so as to space the flat part from the scalp. A tab l6connects with a portion of the part I! of'the cap H for facilitatingseparation of the parts ll 1 and H.

In some cases it is preferable to make the screen i 6 of two sections asshown at 6' in Figure 6 with the sections hingedly connected together asshown at i1 andthe opposite ends of the two 20 sections are formed withdouble curves as shown at 18 in Figui-e 8 so that when these parts are Iforced together in overlapping relation the screen will be held inclosed position. This form of screen facilitates the placing or thedevice over a fan 25 used for cooling purposes and the like and Figure 7shows the screen provided with an angle flange i 9 which abuts the largeend of the casing 5 and the screen is held in"position by the screws 20passing through parts of the 'flange into'the threaded sockets in themembers 2i in the'casing, as shown in Figure '7.

Figure 1 shows a plurality of the delivery members composed of the partsII and i4 connected by hose 9 with the nipples 8 and it will, of course,be understood that as many of the devices can be used as desired.

As is well understood burns are caused usually by steam forming underthe clamps and due to the solution being heated by electrically heatedclamps. My delivery devices are so constructd and shaped that they canbe placed between the clamps, with the ribs l5 spacing the straight partof the rubber member from the head so that the air from the fan passingthrough the hose and escaping through the elongated opening formed bythe rubber member will prevent the formation of steam under and adjacentthe clamps and thus there is no danger of the person having her hairwaved being burned. 7

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be 55 made in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall .within the scope of the appended claims.

What is claimed is:

1. In a device of the class described, a cap, a rubber member flaringoutwardly from the discharge end of the cap and forming an elongatedopening for the cap and said member having a substantially flat outerportion surrounding the opening.

2. In a device of the class described, a cap, a rubber member flaringoutwardly from the discharge end of the cap and forming an elongatedopening for the cap and said member having a substantially fiat outerportion surrounding the opening, and spaced ribs on the flat part forspacing the same from the scalp.

3. In a scalp blower, a cap having an elongated discharge end, asubstantially channel-shaped member held in the discharge end, a rubbermember having one end held in the channel-shaped member and said memberflaring outwardly around the discharge opening and terminating in asubstantially flat outer part, and ribs on said part for'spacing theflat part from the scalp.
